Describes the preparation of different alloys of aluminium with magnesium and zinc. All these alloys were found to tarnish in time, so that they could not be used for permanent mirrors. The best in this respect was the compound Al/sub 3/Mg/sub 4/, and for this alloy a reflectivity of 92% was obtained at 0.7 ?. The zinc alloy was found to have a minimum reflectivity at 0.9 ? and a similar minimum was found for pure zinc at 1 ?.
